BRAKE-CLUTCH.

Specification of Letters Patent.

Patented sept. 22, 1914.

Application led December 13, 1913. Serial No.'806,354f' To all whomz't may concern.:

Beit known that I, JOSEPH HLAszrrsKA, a subject ct' the Emperor of Austria-Hungary. residing at Detroit, in the countyof lVayne and State of Michigan, have 1n.- vented certain new and useful Improvements in Brake-Clutches, of which the following` is a specification, reference being had accompanying drawings.

This invention relates to a brake clutch specially designed for automobiles and similar vehicles.

The primaryy object of my invention is to provide positive andI reliable means, in a manner as 'hereinafter set forth, for gripping and retarding the movement off a driven or revoluble body, without subjecting the braking mechanism to stresses and strains caused by the sudden and uneven application of the braking element o r shoe.v

Another object of my invention 1s to lpro- ,vide a hub member with a plurality of shoes arranged to be simultaneously brought into action without undue wear upon any par ticular part of the driven or revoluble element.

Another `object of my invention is to accomplish the above results by a combination of elements that are strong and durable, easy to assemble, andhighly efficient for the purposes for which they are intended.

Reference will now be had to the drawing. wherein, Figure 1 is a longitudinal sectional view ot the brake clutch, and Fig. 2 is a transverse sectional view of the same.

ln describing my invention by means of 'the drawing above referred to I desire to point out that l intend said views as` merely illustrative of an example whereby my invention may be applied in practice, and ilo not limit my claims to the precise arrangement and construction of parts indicated. The following description is there- 'l'ore to be construed broadly as including substitute arrangements and constructions .vhich are the obvious equivalents of those shown.

In the drawing', l denotes a driven element. as a shaft and mounted upon said shrt't is a hub member comprising a disk 2 having a peripheral Harige Extending into the hub member is the end of an axle 4, which has a casing The casing 5 is termed with an integral circular web (i ex-l tending into proxin'nty to the edges of the annular Harige 3 of the hub member whereby said hub member is the contents thereof stone bruises and the inner side of the web 6 is provided with an annular bearing or collar ,7 and 'mounted upon an annular seat 8 of said collar is a bushing or retaining ring 9. The bushing or retaining ring 9 coperates With the seat S in holding' the. inner edge of the circular fiat slice shifting member 10 arranged within the hub member and having the periphery thereot1 contiguous to the flange 3. The periphery ol the shoe shifting inember 10 is provided with equally spaced cnt away portions or recesses 11 and at one end of each recess is a boss 12 provided with a stud or pin 18. The stud or pi'n 13 extends through an oblong opening or `s'lot- '14 provided therefor in the thickened or reinforced .portion 15 of a web 16, the web forming part of a segment shaped shoe 423 having a wear plate 1T for frictionally engaging the inner side of the flange 3. The shoes are four in number and the webs 1li of said shoes are provided with slotted enlargements 18 to receive studs or pins 19 carried by bosses 2() forming part of the web 3 of the casing 5. The cut-away portions or recesses l1 of the shoe shifting member 10 provide clearance for the bosses 2O and the slotted enlargements 18 are disposed at substantially right angles to the oblong openings or slots 14 of the web 1G.

iametrically opposed edges of the shoe shifting member l0 are provided with pins 20 connected by coiled retractile springs 21 to pins 22, carried by the Aweb 6 ot the casing 5. The member lO is cut away sufiiciently to provide clearance tor the pins 92. The tension of the springs 22 is sutlicient to retain the shoes 23 in a retracted position out of engagement with the flange 3.

The collar 7 and the retaining ring 5l are cut away, as at 94 to provide clearance for a bearing 25 forming part ot' the web G. A rock shaft 26 is journaled in the bearing "25. said rock shaft having the inner end thereof provided Vwith a bifurcated crank 2T which is pivotally connected by a link 28 to the side of the shoe shifting member 10. The outer end of the rock shaft 26 has a crank Q9 adapted to be connected to a suitable operating mechanism (not shown).

Then the shoe shifting men'iber l() is partially revolved upon the retaining ring Si, through the medium ot' the element 25 to 29 practically closed and protected 'from dust,

forces of nature. The

inclusive, the studs or pins 13 'ride against the Walls of the oblong openings or slots'14 and the Webs 16 of the shoes 23 are shifted whereby the Wear plates 17 of said shoesare brought into contact with the flan-ge 3 of the hub member. The braking action of the shoe is distributed throughout the circumference of the fiange 3 and not upon one side thereof, thereby eliminating stresses andstrains upon the brake operating mechal nism. With the slotted enlargements 10 disposed at right angles to the oblong openings or slots 14, the shoes 23 are moved at a tangent to the direction of movement of the shoe shifting member and immediately upon the brake operating mechanism being released, the springs 21 restore the shoe shifting member to its normal position lwhereby the shoes :23am retracted.

What I claim is z- In a brake clutch, a hub member having a flange, a stationary member extending into said hub member, a revoluble shoe shifting member supported between said stationary -lii'ember and said hub member, spaced shoes arranged between the periphery of said shoe shifting member and the flange of said hub member, webs forming part of said shoe at the inner-side of said shifting member,l said Webs havingv long and short slots formed .l

therein with the short slots disposed at right angles to said long slots, studs carried by said shifting member and extending into the long slots of said Webs, studs carried by said stationary member and extending into the short slots of said webs and coperating with the first mentioned studs in guiding said shoes in a radial direction, means eX- tending through said stationary member and connected to said shoe shifting member to facilitate moving the same whereby said shoes are shifted into en agement with the flange ofr said hub mem er, and means at diametrically opposed points connecting said stationary member and said shoe shiftin member adapted to restore-said shoe shifting member to its normal position.A

In testimony whereof I ax my signature in presence of two witnesses.
